      abstract = {Container experiments were conducted in the Dominican  Republic to determine the effect of gibberellic acid-3  (GA3), folcysteine and kinetine on the competitive ability  of eggplant against the weed purple nutsedge. Eggplant  transplants were treated with the growth regulators  immediately before transplanting. The rates were 25 and 50  ppm for GA3 and kinetine, and 250 and 500 ppm for  folcysteine. The competitive ability of eggplant against  nutsedge was determined by relative crowding coefficients  (RCC) in a replacement series with five eggplant to purple  nutsedge proportions (4:0, 3:1, 2:2, 1:3 and 0:4). Kinetine  and folcysteine were not effective in increasing the  ability of eggplant to compete against purple nutsedge.  When no plant growth regulators were used, eggplant was  more competitive than nutsedge. As GA3 was applied at a  rate of 25 ppm, eggplant competitiveness raised with  respect to the control for the 3:1 (+73%), 2:2 (+107%) and  1:3 (+24%) ratios, whereas purple nutsedge RCC values  decreased 33, 50 and 50% for 3:1, 2:2 and 1:3 proportions.  When 50 ppm of G A3 were sprayed, eggplant aggressivity was  enhanced even further with increases of 98, 104 and 55% at  the 3:1, 2:2 and 1:3 proportions.},
